Store full window-configuration with ivy-push-view

[alfaromurillo]

• ivy.el (ivy-push-view): Save ivy-view as a window-configuration object.
  (ivy--switch-buffer-action): Allow restoring a window-configuration object.

This fixes issue #584.

There is a problem with this approach: killed buffers can't be brought back via a window configuration.

You are right. When I have some time I'll check desktop.el to see
if there is a way to use it to recover a frame including its
closed buffers. Seems like even reopening all files before

recovering the window configuration doesn't work.

The ability to save named windows configurations would be very useful, and although there are many attempts out there, none of them work on emacs > 25, at least not for me. So I really hope this work will be completed.

Also, I hope that it will also save and restore indirect buffers, which are made, for example, by org-mode.
